Hi, the TV will only work with the Sony Dongle - UWA-BR100 USB Wi-Fi® adaptor.
The reason for this is as follows: When you use a USB Dongle on a computer, you will need to install software, so that the computer knows how to use the Dongle. You cannot do this with a TV. Sony pre-install the software for this particular Dongle, so that you can just plug it in to the TV and it should work.
Hope that helps...
